Window module and window as well as laser demarcation device with window

Abstract

The invention provides a window module. The window module comprises a front window, a left window and a right window which are vertical to the same plane, wherein an isosceles trapezoid is formed by projections of the front window, the left window and the right window in the plane. The window module can be used for eliminating parasitic light on the basis of the prior art so that the brightness of horizontal laser rays projected by a laser demarcation device is balanced.

Description

technical field [0001] A first aspect of the invention relates to a window module. [0002] A second aspect of the invention relates to a window with the window module. [0003] The third aspect of the present invention relates to a laser line projector with the window. Background technique [0004] With the continuous development of laser wire casting equipment and the continuous expansion of its application range, customers have higher and higher requirements for laser wire casting. [0005] For example, more and more customers require that the laser line projector can project a 360-degree laser line, that is, the laser line can achieve full-angle coverage in a single plane. However, in the previous traditional laser line projectors, to achieve a 360-degree laser line, it is usually necessary to set up a laser module every 90 degrees in a plane, and the laser line projected by each laser module has a diffusion angle of about Between 120 degrees and 150 degrees, a total ...

AI Technical Summary

Problems solved by technology

This leads to such a laser line projector occupying a large space and a high cost of materials.

[0006] In this regard, the existing technology has proposed a 360-degree laser line projector with a small footprint and low cost, but the laser line projector still has some defects, that is, stray light will appear in the part with a large angle
